HYDRAULIC MACHINE.

Application filed November 17, 1922. Serial No. 601,456.

To all whom it may concern:

Be it known thatv FRED C. PAA'rsoH, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, has invented a certain i new and useful Hydraulic Machine, of which the following is a specification.

This invention relates in general to improvements in the construction of hydraulic machines, and relates more specifically to an improved frame and housing structure for impulse water wheels and the like.-

An object of the invention is to provide an improved frame structure for hudraulic machines, which is simple, compact and rigid in construction. Another object of the invention is to provide simple and efficient means for housing hydraulic machines and the like.

It has heretofore been customary in the construction of hydraulic machines such as impulse water wheels, to provide each machine with a sheet metal readily removable cover supported by a special cast. metal frame. These cast metal frame structures of the prior art were very costly and were difficult to transport and to install.

The present invention contemplates provision of a frame structure especially applicable to impulse water wheels, which is formed entirely of structural steel of standard cross-section. Such a frame structure besides being much cheaper to construct, may be more readily transported and installed and produces a more rigid and neat assembled frame structure. The struc tural steel bars may be out -into.suitable v lengths and fitted in the shop, after which the frame maybe disassembled and shipped in relatively compact form to the destina-- companying and forming part of this specification in which like reference characters designate the same or similar various views. r V

Fig. 1 is a vertical section through an impulsewater wheel installation embodying a frame constructed of structural steel-bars having standard cross-section.

parts in the Fig. 2 is a fragmentary transverse vertical section through the nozzle pit of an improved impulse water wheel installation. v Fig. 3 is an enlarged fragmentary transverse vertical section through the frame structure of an installation such as illustrated in Fig. 1. r

Fig. 4 is an enlarged fragmentary transverse vertical section through a modified impulse water wheel frame structure,

The hydraulic power installation illustrated in Fig. 1 comprises in general a rotor 2 mounted upon a horizontal main shaft 3 and having a series of peripheral buckets adapted to receive a jet of waterdelivered from the nozzle 4 in line with an adjustable control needle 14. The upper portion of the rotor 2 is inclosed by a removable sheet metal cover 5 having an angle bar 6 secured thereto by any suitable method such-as by riveting or welding. The angle bar 6 has a flange formedfor coaction with the upper flange surface of a structural steel channel bar 7 as indicated in Figs. 1 and 3, the'angle iron 6 and channel bar 7 being detachably connected by means of a series of bolts 15 which are readily accessible from the easing exterior. .The lower flange of the channel bar 7 coacts with a liner plate 10 and is embedded in the concrete foundation 9 as indicated. A dripcatch channel bar 8 which is also preferably formed of structural steelof standard cross -sec tion, extends longitudinally of the channel bar 7 and is preferably secured thereto by means of rivets orby welding. This drip catch channel bar 8 may be located at any convenient place relatively to the bar 7 so that drippings from the oover 5 and other elements will collect in the channel bar 8 from which they may be conducted in any suitablemanner. The channel bars 7, 8 are. preferably formedin sections of convenient length for transportation, and

. beddedin the concrete of the foundation 9. -The nozzle 4 adjacent to the bar 13 is encircled by a standard angle bar 11 one flange of which engages the periphery of the nozzle 4 and the other flange of which coacts with a sealing plate 12. The sealing plate 12 is preferably formed of sheet metal and engages an end of the channel bar 13 so as to completely segregate the interior of the wheel casing from the nozzle pit.

In the modified constructions of the frame 7 illustrated in 4, one of the elements,

namely the angle bar 6, isdispensed with and the drip channel bar 26 which is secured directly to the cover 25 serves as an intermediate support between the cover 25 and the frame channel bar 27. The drip catch channel 26 is detachably-connected tothe upper flange of the channel'bar 27 by fmeans of bolts'30 and the lower flange of the channel bar 27 coacts' with a lining' plate 28. The concrete foundation 29 en- ,gages'the channel bar 27 and the lining 28, the latter elements preferably being anchored to the adjacent concrete in any convenient manner. The channel bars 26, 27 are preferably formed in sections of convenient length' for transportation, the adjoining ends of the sections being provided with suitable connecting means. 7

It will be obvious that the use of structural steel bars of standard commercial crosssection, reduces the cost of construction to a minimum. The strength of the assembled structure may be made equivalent to that of a much heavier cast metal frame such as previously used. By making the structure sectional, the Various elements may be shipped in-relatively compact form thereby greatly facilitating transportation. The as- 'sembled' structure presents an extremely neat and Imech'anical appearance and is readily assembled and dismantled.

It should be understood that it is not desired to limit the invention to the exact details of construction herein shown and de- Y, scribed, for various modiflcations within 1 the scope of the claims may occur to perv sons skilled in the art. 4

1 It is claimed and desired to secure by Letters Patent 1.
